Hi,
I'd like to verify I've understood your problem correctly. Does the graphical component on your panel show something like 'Laptop battery (100%)'?
Then you can get version of this component in terminal using:
$ rpm -q gnome-power-manager
Try in terminal also
$ acpi
when power supply is on and off. This should generate output:
AC on:
Battery 0: Unknown, 95%
AC off
Battery 0: Discharging, 96%, 01:49:51 remaining
Wait a second to call acpi command after switching off AC. Firstly you should get info laptop runs on battery.
Try to update gnome-power-manager (or reinstall # sudo yum reinstall gnome....).
Output of devkit-power seems to be ok.
Thanks, Jiri

Alright, I've tried a couple different things. First off, to answer your questions above:
1.) rpm -q gnome-power-manager
gnome-power-manager-2.30.1-1.fc13.x86_64
2.) acpi (on)
Battery 0: Charging, 28%, 01:39:20 until charged (at this point, gui shows
Battery: 100% charged, 0:-28 until full)
acpi (off)
Battery 0: Discharging, 29%, 01:17:42 remaining (at this point, gui shows
Battery: 100% charged)
Also, I did attempt to reinstall, but there was no luck.
From what I was seeing, and the pattern you can see above, it appears possible the percentages and time remaining may be reversed. See the results when acpi is on. This is just a theory, I don't have the code to tell what is occurring, but thought maybe I'd throw that theory out there.
Thanks!

Thanks for your tests. This is strange. You have exact the same g-p-m as mine. I've heard about earlies issue in upower but your output seems to be correct.
Well, let's ask g-p-m & upower maintainer. Richard do you have an idea what's wrong?

Also, I should note that when I completely exhausted the battery, then plugged it in and started recharging it, the battery manager only took a few seconds to show 100% charged, although according to the terminal printout there was approximately 2.5 hours until the battery was 100%. So, in short, it's not that it always shows 100% as it turns out. When the battery level got extremely low (~20%), the battery manager began updating the GUI display. Then, when charging from dead, the battery manager started showing no bar on the GUI (no charge) and quickly drew the bar up to 100%. Thought I'd share this if it further details the problem any further to help diagnose the issue. Also, a friend mentioned that it could be a problem with the bios reporting, but I'd assume that if that was the case, the acpi would also have incorrect information, correct?
Thanks!

How did you add the battery monitor to the panel? Via
Panel Settings -> Panel Plugins -> Add -> Battery Monitor?
What does it look like? Is there an icon or is it just a green bar?
If so, what you are seeing is a duplicate of bug 561311.

It was Right Click (on toolbar) -> Panel Settings -> Add -> Battery Monitor. This is probably the same as you were saying. There is just a green bar that, when hovered over, shows the remaining time and battery percentage. Is there another battery monitor that I could try out and add into the panel?
I will check out the bug you linked to.
Thank you.
